Hello,

the problem have been resolved by setting in Clover bootloader ACPI option "Fix audio" and booting OSX Sierra.

Once the problem was fixed I used MaciASL to recompile DSDT and following boot confirmed that the problem is resolved.

 

https://sourceforge.net/projects/maciasl/

I include final DSDT.aml file just in case if somebody has same problem. With this DSDT.aml file computer goes into sleep mode and wakes up perfectly.

NOTE: I have add-on video card Geforce 9500 and if you have different video card then you might require to "tune" your DSDT.aml file (not sure if it will require)

 

Thanks
